+This function posts an event to be processed later.

+\wxheading{Parameters}
+
+\docparam{event}{Event to add to process queue.}
+
+\wxheading{Remarks}
+
+The difference between sending an event (using the
+\helpref{ProcessEvent}{wxevthandlerprocessevent} method) and posting it is
+that in the first case the event is processed before the function returns,
+while in the second case, the function returns immediately and the event will
+be processed sometime later (usually during the next event loop iteration).
+
+A copy of {\it event} is made by the function, so the original can be deleted
+as soon as function returns (it is common that the original is created on the
+stack).  This requires that the \helpref{wxEvent::Clone}{wxeventclone} method
+be implemented by {\it event} so that it can be duplicated and stored until
+it gets processed.
+
+This is also the method to call for inter-thread communication---it will
+post events safely between different threads which means that this method is
+thread-safe by using critical sections where needed.  In a multi-threaded
+program, you often need to inform the main GUI thread about the status of
+other working threads and such notification should be done using this method.
+
+This method automatically wakes up idle handling if the underlying window 
+system is currently idle and thus would not send any idle events. (Waking
+up idle handling is done calling \helpref{::wxWakeUpIdle}{wxwakeupidle}.)
